Direct benefits to the participants, who are diagnosed with celiac disease may be substantial and could include lessening or prevention of GI symptoms, correction of biochemical abnormalities and reduction in risk for malignancies or bone disease which are most common in untreated celiac disease. However, the precise benefit is unknown and the motivation for this proposed study. If these individuals have a positive celiac serology test at the present time there is a high likelihood that they may have celiac disease.
